FEATURES

  • The CXA-P1212-VJL is an inverter for cold cathode fluorescent lamps and features a built-in dimmer.
  • Because they employ advanced output current control, fluctuations in input voltage, load, and distributed capacitance have virtually no effect on brightness.
  • Output open and short circuit conditions result in no damage, heat generation, or other difficulties.
  • Safe design that includes a built-in overcurrent protection element.
  • Insulation is simplified due to flat backside surface of board.
  • The high-voltage terminal is coated with silicone so as to reduce a possibility of an occurrence of a defect caused by dust.
